These pages chronicle my investigation into a little DIY favorite, the Sonic Impact digital amp based on the Tripath TA2024 chip, as well as some new T-Amps.

For newer audio adventures, please see my new site. www.michaelmardis.com

There are now a lot of good T-amps on the market. You can see 2 of them on these pages. The Super-T and the Trends Audio TA-10. Check them out.

Also visit 41Hz.com, for great T-Amp kits. (The AMP6 is my favorite).

If you wish to skip all the text and go right to the facts, have a look at the FAQ page, and/or look at the bottom of each page were there will be a summary of the page.

The Tripath chip is a switching amplifier that uses a spread spectrum PWM technique to generate the audio output. This output is then filtered through a simple 2nd order low pass passive filter to remove the ultrasonic switching residue and leave the audio signal that is sent to the speakers

On the right you will see a typical application circuit for the TA2024

There are a number of threads on the audio forums that discuss this little Class-D amp and modifications to it. I believe that I first came across it HERE on the DiyAudio Forum.

There are threads about this amp on:
Audio Asylum
Audio Circle

as well as reviews on many other sites.

You will notice that the TA2024 is a stereo bridged amp. This is obvious from the schematic as we can see the dual push pull transistors for each channel and the 2 sided output filters. The chip is designed to run off 12VDC, so the bridged mode is needed to squeeze more power out of the 12V.

It CAN NOT be bridged further.
